Aldehyde removal sterilizing weather-resistant environment-friendly latex paint and preparation method thereof

Abstract

The invention discloses aldehyde removal sterilizing weather-resistant environment-friendly latex paint which comprises the following raw materials in parts by weight: 2-4 parts of polyvinyl alcohol, 0.2-0.4 part of sodium hexametaphosphate, 0.05-0.15 part of pyrethroid, 30-40 parts of an acrylic copolymerized emulsion, 1-2 parts of propylene glycol, 1-3 parts of hydroxyethyl cellulose, 20-26 parts of filler, 1-2 parts of a compound processing aid, 2-3 parts of a function enhancing additive, 10-14 parts of an aldehyde removal additive and 20-30 parts of deionized water. The latex paint disclosed by the invention is good in film hardness, high in covering force, good in scrub resistance and long in service life, is free of a bulging fall-off phenomenon, and is high in stability, good in water resistance and acid and alkali resistance and excellent in comprehensive performance. In addition, the latex paint also can purify indoor air, prevent mildews and algae and kill mosquitoes lastingly. The raw materials of the latex paint disclosed by the invention are safe and reliable in component, free of environmental pollution, easily available, relatively low in cost, concise in process, easy to operate and realize industrial production, and has relatively high practical value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an aldehyde-removing, sterilizing, weather-resistant and environment-friendly latex paint and a preparation method thereof. Background technique [0002] Compared with external environmental pollution, indoor air pollution has a more significant impact on health; in newly renovated houses, indoor air usually contains more toxic substances such as formaldehyde (CH2O), benzene (C6H6) and methanol (CH3OH). Especially in a relatively closed environment, toxic and harmful substances exist for a long time, and the probability of various diseases will be greatly increased; therefore, the odor-cleaning paint is also loved by consumers. Existing odor-cleaning paints are added with essence or odor masking agent, which cannot quickly dissipate irritating odors and lack the function of purifying indoor air odors. [0003] On the other hand, due to people's increasing awareness of...

Problems solved by technology

At present, ordinary latex paint has poor scrub resistance, self-cleaning property, acid resistance, alkali resistance, weather resistance and stain resistance. Acid-resistant and alkali-resistant fluorocarbon coatings, because fluorocarbon coatings use fluorine-containing olefins as raw materials and copolymerize under a certain pressure, the production investment is large, the raw materials are expensive, and the cost is high

At present, there is no latex paint with simple production process, excellent scrub resistance, self-cleaning property, acid resistance, alkali resistance, weather resistance, stain resistance, and low cost.
